Factors affecting enzymatic reactions Enzymes specificity Enzymes kinetics and mechanism of action Control of metabolic pathways Enzymes inhibition Enzymes in clinical diagnosis Enzymes and genetic diseases. Definition of an enzyme. Enzyme. is . protein . . catalyst. (i.e. . increase the rate of reactions. ). . NOT. changed during the reaction. Enzymes as Catalysts. Enzymes are used to speed up chemical (metabolic) reactions e.g. respiration or photosynthesis- so why use enzymes in industry?. They are specific. can catalyse reactions between specific chemicals, even in a large mixture . Warm up. Grab warm up and complete. We will be putting this into your . journal. When you are done with your warm up look over your Vocab 1-1, you have a . quiz today. Biomolecule review. Cellulose, a structural component of the cell wall of plants and some forms of algae, is mainly used to produce paper and cardboard products. Cellulose would be an example of which type of biomolecule. Enzymes speed up chemical reactions.. Everything that happens in a cell. Growth. Reproduction. Interaction with the environment. Response to stimuli. Is the result of a chemical reaction.. A chemical reaction is a change in the arrangement. Academic . Biology. Enzyme. A large protein molecule. Specific shape with deep folds on its surface. Deep folds form pockets called active site. Enzyme-Substrate. The shape of the . enzyme. . active site . Are specific for . what they . catalyze . and do not permanently change during reactions. End in the word -. ase. Function of Enzymes. Enzymes work by lowering the activation energy (the amount of energy needed to start a reaction). . IMPORTANCE. OF ENZYMES. Enzymes are biological catalysts that:. .
